LAMP.

SPECIFICATION forming part of Letters Patent No. 534,888, dated February26, 1895.

Application filed September 27,1894:- Sarial No. 524,272. (No model.)

To all whom it may concern:

Be it known that we, HERBERT E. KEELER, of the city, county, and Stateof New York, and WILLIAM S. HAMM, of Chicago, in the county of Cook andState of Illinois, have invented certain new and useful Improvements inLamps, of which the following is a full, clear, and exact specification.

This invention relates to a combination electric and oil or candle lamp,especially adapted for street car and steam railway car use, althoughitis obvious it may be adapted to other uses.

In the accompanying drawings, Figure 1 is an under side view or invertedplan showing our invention. Fig. 2 is an elevation partly in section.Fig. 3 is a longitudinal vertical section of a portion of the inventionon the line 3-3 Fig. 1. Fig. 4 is a transverse vertical section on theline 4-4t Fig. 1.

Similar letters of reference indicate similar parts in the respectivefigures.

Heretofore in certain combination lamps of this general character muchof the illuminating effect of the electric lights has been obstructed byarms or pendants which support the oil or candle lamp, while in otherswhere the electric light bulbs have been placed outside the arms orpendants, they have been too far away from the surface of the reflectorto allow the light to be efficiently reflected thereby. The object ofthe present invention is to overcome such objections in the older stylesof combination lamps by certain novel constructions, combinations andarrangements, as hereinafter specified.

It is to be understood that in this invention, as in similar combinationlamps, the oil or candle lamp is intended for use only in the event ofthe failure of the electric current, or other accident to the electriclights.

A represents a preferred form of reflector made of four sections united,by means of flanges a andrivets b, substantially in the manner shown inFigs. 3 and 4, so as to form a square having ornamental corner pieces 0,

The reflector A is here shown as having four exterior reflectingsurfaces f, and four interior reflecting surfaces g, the latter forminga pyramidal depression, in the center of which ney tube Z over which theordinary wind.

guard or ventilator (not shown) is placed.

The threaded socket 7c is provided with a hole m, into which the pointof a spring bolt n, operated through the medium of a finger piece 0fits, so that when the lamp B is screwed to its proper position it isheld by the spring bolt. The ring it is perforated as at 70, to aid inthe supply of oxygen to the flame.

C, O, G, O are four electric lamps, preferably of the well known GeneralElectric Company type, to which lamps necessary connections forming. nopart of our invention, are made. Each of the lamps 0 passes through oneof the exterior parts f of the reflector, and is attached thereto bymeans of yokes or supports to, so that the longitudinal center line ofeach lamp stands at a right angle to an exterior reflecting surfaces f.It will be seen that the light from the electric lamps is in no wiseobstructed by intervening arms or objects as in some lamps of thischaracter heretofore employed, that the full reflecting capacity of thesurface f outside of which the lamps are attached is uti'lized,and thatno shadows will be thrown. The same is true of the effect of attachingthe central oil or candle lamp B to the reflector itself without the useof arms or pendants. The central lamp B is brought in closer proximityto the re fleeting surfaces 9 than is the case with other combinationlamps of this general character employing pendants or arms in thesupport of the lamp.

The reflector is either attached directly to the deck of the car,ceiling, &c., or to braces or other intervening supports.

The glass globe s of the central lamp is cemented to the rings h and t,as shown in Figs. 2 and 3; while the lower portion v of the lamp isremovable from the ring t by means of a threaded union therewith,

While the reflector is here shown square, and consisting of four similarconnected parts, it may be of octagonal, triangular or other shape, andwith concave, convex offi'at reflecting surfaces. The reflector isprefer ably made of sheet steel having enameled outer faces, but it maybe constructed of sec tions of mirror or porcelain or it may be paintedor eleclroplated. The reflector is furnished with a series of holes winorder thata body of heated air may not be confined within it, whichmight tend to crack the enameling, or otherwise injure the reflectingsurfaces.

Having described our invention, weclatim- 1. In a lamp of the characterdescribed, a A reflector having inner and outer reflecting surfaces asdescribed, an oil or candle lamp placed centrally of the reflector, andsurrounding electric lamps attached to the exi S. HAMM, have hereto setmy hand and seal, at Chicago, this 22d day of September, A. D.

terior portions of the reflectonthe said lamps being supported entirelyby the reflector without the intervention of arms, pendants or othersupports, substantially as set forth. 2. In a lamp of the characterdescribed, a

reflector having a central annular socket, and

a lamp adapted to be reinovably attached thereto, and a chimney tubeconcentric with the annular socket and attached thereto, and electriclamps detachably secured to the reflector around the central lamp,substantially E as set forth.

In testimony whereof I, the said HERBERT I E.-KEELER, have hereto setmyhand and seal,

at New York, this 24th day of September, A. D". 1894.
